All non-Annex I Parties are required to submit a national inventory of anthropogenic emissions
by sources, and removals by sinks, of all greenhouse gases (GHGs) as part of their national
communications. The secretariat developed a web-based application for use by non-Annex I
Parties in estimating and reporting their GHG emissions by sources and removals by sinks. It is
accessible here:https://unfccc.int/naiisapp/view/listSubmission.jsf

The table below explains different levels of the access rights and corresponding explanation for each
role. It is important to note that the roles are not necessarily identical to a person’s title
(e.g. NFP) and that a person can take on several roles (which may be necessary for some
countries).

Type of access rights

Process to gain access rights

NFP: Will be responsible for identifying the members of the team and is the
only one who has the right to approve the submission.

NFPs will be able to create, edit, update or delete all of their country’s GHG data
entries and grant access rights to ‘Project manager’ and 'Sectoral
experts' for their country if they choose to.

For the purpose of this NAIIS web application, the NFP can be any expert/member
nominated by the NFP for the UNFCCC, on behalf of its country.

Parties that have not already requested and received access rights can obtain them by having
their NFP contact: naiisapp@unfccc.int

(Note: Some Parties may have more than 1 individual acting as NFPs; however the system can
accommodate only 1 account per Party)

Project manager: Will have rights to enter/edit data in all sectors, as well
as to generate official submission.

Entities will be provided these rights by their NFP. If a Party decides to grant access to a
PM, their NFP will be able to create such user account on the NAIIS application.

Sectoral experts: Will have rights to enter/edit data in respective sector(s).

Experts will be provided these rights by their NFP. If a Party decides to grant access to
Sectoral Experts, the NFP will be able to create such user accounts and assign them in
respective sector(s).

NAIIS - Summary and background

As per Article 4, paragraph 1 (a), and Article 12, paragraph 1(a) of the Convention, non-Annex I
Parties are required to communicate to the Conference of the Parties a national inventory of
anthropogenic emissions by sources and removals by sinks of all greenhouse gases (GHGs) not controlled
by the Montreal Protocol, to the extent its capacities permit, following the guidelines contained in
annex to decision17/CP.8.

In order to facilitate non-Annex I Parties in developing and reporting their GHG inventories as a
part of their national communications, the secretariat developed an Excel-based software which
incorporated all the elements of a national GHG inventory prescribed by decision 17/CP.8. The
software was based on the IPCC inventory software version 1.1 which used the Tier 1 methodologies for
estimating GHG emissions and removals for all source categories described in the Revised 1996 IPCC
Guidelines, and further complimented by GPGs.¹

Since its release in 2005, most non-Annex I Parties have been using that software for development of
their national GHG inventories. In June 2011, Parties requested the secretariat to upgrade the
software and make it available to non-Annex I Parties by June 2013. Pursuant to that request, the
secretariat upgraded the current Excel-based version of the software (v.1.3.2)² into a web-based
application that provides greater degree of flexibility in using it as well as enable a prompt
upgrade of the application to respond to any possible methodological changes that may occur in the
UNFCCC process, such as the possible switch to the use of the 2006 IPCC Guidelines in the reporting
of national GHG inventories by non-Annex I Parties.

Upon request to the secretariat, each non-Annex I Party will be provided with an access to a password
enabled working space in the web-based application. The individual working space will contain the
following functionalities:
